Hi @skrap, thanks for the link, that really helps, it now makes sense.
Thank you for the PSU project feedback, I am still working on the PSU, I have not given up
. I am have way through the 14th episode, am getting some good results in the basic response measurements, not quite as good as my HP benchmark but very good none the less. Its taking me longer now because I am at levels of detail that I am not so proficient or experienced so I am having to learn a lot to make progress.. will hopefully push the next article out in a few days time.
